I have a 1998 328i. I have recently replaced the tie rods control arms, control arm bushings and the rear trailing arm bushings. Then I bought new rear tires. I then had a 4 wheel alignment done. Then I bought new front tires.
Now there is a bit of a vibration or shake when the speed is up to 70mph. I didn't drive it much between the purchase of the two pairs of tires. Oddly it doesn't seem to do it all the time.
Any ideas what this may be?
